FORCE-FEED LUBRICAT'OIIR.

Toall whom it may concern; i

Be it known that I, CLARENCE B. HODGES,

' residing at Detroit, in the county of Wayne and State of Michigan, acitizen of the United States, have invented certain new and useful- Improvements in Force-Feed Lubricators of which the following is a specification, reference being had therein to the accompanying drawrn s.

The invention relates to force feed lubricators, and consists in the construction of a lubricator comprising a rotary valve having an axially arranged cylinder, a piston there- I in, and means for operating the piston by-the rotation of the valve, and a second piston connected to the first and adapted to supply the oil to the firstementioned piston, passing the same through a sight-feed device.

Theinvention further consists in. the construction, arrangement and combination of the various parts as more fully hereinafter described and particularly pointed out in the claims.

In thedrawin s, Figure l-is a vertical central longitudina section through myfimproved device; Fig. 2 is a similar section at right angles to the section line of Fig. 1; Fig. 3 1s a horizontal section on line w'x of Fig. 1; Fig. 4 is a horizontal section on line y y, Fig. 1'; and Fig. 5 isa horizontal section on line a b of Fig; '2. e

A representsthe reservoir, adapted to take the oil whichis desired to be pumped to various points of lubrication, as, for instance,

as this device is particularly intended, foruse in an automobile.

The reservoir top is provided witha central screw-threaded aperture into'which is screwed the valve casing B, having a tapering chamber therein in which is located a tapering valve B. This valve at its upper end has a v spindle a projecting through a suitable apertightly to ture in the upper part of the valve casing, and carries the collar a at its upper end. Beneath this collar is a spring? resting on a shoulder c, the spring acting to hold the valve upper portion of the valve is formed into or provided with a su 5 itable worm wheel D, with which'a' worm on the shaft D is adapted to engage, as particularly shown in Fig. 4.

This forms the drive shaft for the device, and

is driven from any suitable source of power.-

The valve isprov'ided with an axially arranged-cylinder d, in which is the pisto'n d having a head E just below the valve. This I induction port its seat in the valve casing. The" Patented ma' es, 1907.

head is provided with the roller-wr sts E engaging in a camway F formed upon the two stationary collars G- and G, the proximate faces of which are shaped to give the necessary'movement to the piston, and as particularly shown in Fig. 2. Upon the opposite side of the head E is ashaft or extension H, formirlrg another piston, which works in a cylinder which I have shown in this case as supported upon-the lower edge of the valve casin This cylinder has the induction port e' lea g into the reservoir and the eduction passage h which leads into a vertical passage 'i,-the usual check valve lc being interposed. The passage .11 I have. shown as formed in the valve casing and extending to the top thereof, where it conmiunicates into a chamber Z In the bottom of this chamber Z are a series of nozzles m, each controlled by a suitable needle valve n, adjustably secured in the nuts n which are screwed into apertures in the top of the valve-casing. The nozzles depend into a-sight-feed chamber 0, which is provided. with a suitable lass 1-, through which, all the nozzles may e inspected. I have shown a single glass for a single chamher 0, but it is obvious that if desired separate lasses maybe arranged for separate v .cham erswithout in any way departing from my invention.

inder d. I

The, valve is provided with a cross-passage u at the end of the cylinder, and opposite the or passaget are a corresponding series of e-duction ports, or passages 11. In order to cause valve, 1 provide the engaging in suitable beside the piston.

pins I on the headE,

Below each nozzle is a passage 8 communicating with an inlet pasapertures in the valve wrists E ensage or port t opposite the upper-end of the the piston to rotate with the The parts beingthus" constructed, their nozzles m, falling into the passages s and will be drawn in through the induction passages tby the piston d. The oil drawn in by the piston d to the cross-passa e a when that passage is in registration wit one of the induction ports will be forced out through one of the passages v when the other end oi the cross passage registers with such eduction port and thus the pump in the valve will successively take the oil from the passages t and deliver it successively into the passages v and thus lubricate the various parts to which th'esepassages connect. It is obvious'that the desired amount of oil for each part to be lubricatedcan be regulated by ad: usting the valves n. In case the ump, H delivers'more ,oil into the chamber than is allowed to pass out the nozzles m, I provide a spring-pressed check valve J in that chamber so that upon pressure being developed therein above. the normal this valve will be raised from its seat and theoil will flow back into the reservoir'to be pumped over again.

K is a suitable filling aperture.

It will he observed that in this construction a single actuating means operates the valve and both pistons, and that the device isextremely simple and compact and yet I am enabled to deliver oil from a single reservoir to a number of different points and with the use of a single delivery pump.

What I claim as my invention is 1. In a force feed liibricator, the eombina-.

tion of a reservoir, a tapering cylindrical valve. casing, a rotary valve in the valve cas-v ing, an axially arranged cylinder and iston inlthe valve. forming a pump, means or 'rotating the valve and for thereby reciprocating the-piston, there being a cross passage in the valve communicating with the inner end "of the cylinder, andinletand outlet assages on opposite sides of the casing wit which said cross passage is adapted to connect in the rotation of the valve.

2. In a force-feed lubricator, the combination of, a reservoir, a valve casing therein, a

rotary valve in the valve casing controlling the inlet and exitvportsof a pump, the pump, a second pump operated by the rotation of the valve, adapted to take the-oil from the reservoir and deliver itto a regulated sightfeed chamber, and; a connection vfrom the sight-feedchamber to the inlet portof the first mentioned um In a forceeed ihbricator,thecOmbination of a. reservoir, a valve casing therein, a rotary valve in the casing, an axially arranged cylinder in th'evalve, a fpiston therein 1 turning with the valve, means or reciprocating-the piston by the rotation of the valve, a

second piston formed as an extension thereof, a cylinder in which said piston works, connected to take oil from'the reservoir and deliver it to a chamber at the top oi the reservoir, a series of valve-controlled sight-feed devices leading from the chamber to induction ports in the valve casing, there being a cross-passage in the valve adapted to successively connect with these induction ports, and with eduction ports opposite thereto.

4. In a force-feed lubricator, the combination of a rotary valve, an axially arranged cylinder therein, a reciprocating head having oppositely extending pistons thereon, one piston entering the cylinder in the valve, a cylinder for the other piston having an induction port connecting to the reservoir, and an eduction port leading through a sight-feed passage to the valve, and a passage in the valve adapted to connect with inlet and outlet ports.
